Checkout the live demo here http://borderguru.herokuapp.com/
Make sure you have Node.js and mongodb up and running.
$ git clone https://github.com/madhums/borderguru.git
$ cd borderguru
$ npm install
$ export NODE_PATH=./config:./app/controllers
$ export NODE_ENV=development
$ npm start
Then visit http://localhost:3000
Main application logic can be found in order controller and order model
P.S: Part of this setup has been taken from my own boilerplate which can be found here
